2021 article

Exploring secondary interactions and the role of temperature in moisture-contaminated polymer networks through molecular simulations (vol 17, pg 2942, 2021)

Guha, R. D., Idolor, O., Berkowitz, K., Pasquinelli, M., & Grace, L. R. (2021, May 28). SOFT MATTER, Vol. 5.

By: R. Guha n, O. Idolor n, K. Berkowitz n, M. Pasquinelli n & L. Grace n

TL;DR: The results obtained imply that the polyene-like structure dominates in the liquid phase while in the solid phase the polymethine-like structures are more likely to be affected by the temperature. (via Semantic Scholar)
